Groove cooperation.This cooperation between the flexible pawl 110 of main body 1 and the guide profile of actuating sleeve 10 can realize that actuating is opened
The startup locking and the locking of home of beginning is equivalent to the second projecting positions of the actuating sleeve.
As described in document WO2013175140, WO2013175142 and WO2015075399, flexible pawl 110 is in the guiding
It is lateral and/or move radially in type face, to ensure the startup of automatic injector and then lock, therefore the reliability service of the flexibility pawl
It is critically important.However, before actuating, and during no dismountable the cover 20, spring 9 pushes actuating sleeve to its first projection
Position, therefore, the head of flexible pawl 110 is at the contact point C between the flexible head of pawl 110 and the convex shoulder 13 of main body 1
Under the stress of the spring, the bottom wall of the guide profile is limited, particularly limits initial trench 100.Contact point C exists
It can see on Fig. 2 d.
However, the active force that spring 9 applies at contact point C has the tendency that being stretched by flexible 110 axial deformation of pawl.This
Kind tensioning may change the mechanical strength property of flexible pawl 110, therefore reduce its performance, in needle safety at the end of particularly activating

According to the present invention, the fixation of dismountable the cover 20 on the body 1 causes actuating sleeve 10 axially upwardly to move, from
And make the flexible pawl from the stress release for being subjected to spring 9.
More precisely, when dismountable the cover 20 is fixed on the body 1, actuating sleeve 10 axially upwardly moves (i.e.
To the direction of the distal portions of main body 1) a distance d, mild compression spring 9.As on Fig. 1 d it can be seen that, then main body 1
It is not in contact between the head of convex shoulder 13 and flexible pawl 110, this axial stress that flexible pawl is just made to apply from spring 9 releases
Come.Therefore, the fixation of dismountable the cover 20 on the body 1 should be more stronger than the active force that spring 9 is applied on actuating sleeve 10.
In fact, when being not in contact between flexible pawl 110 and the convex shoulder 13 of main body 1, the active force of spring 9 is applied to removably
In the cover 20, actuating sleeve is maintained at the position for the distance d that is staggered upwards by dismountable the cover.Therefore, the active force is more accurate
Ground, which is applied to, fixes dismountable the cover 20 in fixed component on the body 1, i.e., in the example shown, fixes in fig 3b
On the air ring 15 and 25 that can see.Therefore user should be more than spring 9 application active force axial force axially downwardly
Dismountable the cover 20 is pulled down, so as to remove the cover from the main body 1.
When user removes dismountable the cover 20, spring 9 will make the actuating sleeve move axially downwards institute
Distance d is stated, brings it to the first projecting positions, in first projecting positions, as can be seen on Fig. 2 d, the head of flexible pawl 110
Portion is contacted with the convex shoulder 13 of main body 1.
Fig. 3 a and 3b shows do not have the position of the cover with right side with position of the left side with the cover in figure in two different directions
It puts and compares, when dismountable the cover 20 is fixed on the body 1, the upward displacement distance d of actuating sleeve 10.
Therefore, two locks of actuating sleeve, that is, the locking lock spy started after lock and actuating before activating
It is not effectively and reliable, while mold and assembling are firm, easy and therefore cheap.Particularly, lock only includes two components,
Actuating sleeve 10 and main body 1.
Of course, it is possible to change the shape of guide profile and flexible pawl with desired feature as needed.
It is noted that above-mentioned component can be made of opposite mode, i.e., main body 1 can include guide profile, and outstanding
It is initial trench 100, and actuating sleeve 10 can include flexible pawl 110.
Especially, the present invention is applied to the device that uses for the treatment of autoimmune disease, such as rheumatoid arthritis, a variety of
Sclerosis, Crow grace type disease, for anticancer therapy, for antiviral therapy, such as hepatitis, for treating diabetes, for poor
Blood is treated or is broken out for allergy and treats, such as in the case of anaphylactic shock.
Although with reference to an Advantageous embodiments, invention has been described, certainly, those skilled in the art can
